Globe Valves
-
High thrust cylinder actuator.
-
Easily reversible and features exceptional stiffness, repeatability, and low hysteresis.
-
Globe-style bodies feature smooth, streamlined, constant-area internal passages with no pockets, permitting high capacity with minimum.
-
Bonnets are designed to permit a wise variety of packing configurations, including a double set of packing, without changing bonnets.
-
ValtekSul offers environmental packing systems as ISO 15848-1, FCI 91-1 or TA-Luft
-
Double-stem guiding located out of flow stream eliminates galling associated with cage guiding self-aligning seat ring.

ValtekSul offers environmental and
non-environmental packing systems.
​
The non-environmental packing systems also provide goog leakage control, their more simple materials and designs will usually leak at higher levels and will not maintain to long time ultra-low leakage.
​
The environmental packing systems are designed to provide less than 500 ppm service for typical control valve applications.
​
The live-loaded packing systems maintain
a constant sealing force within the packing box, providing low leakage performance with minimal field adjustment.
​
Envoronmental packing systems that have been tested and certified, meeting such standards as ISO 15848-1, FCI 91-1 or
TA-Luft.
